Placing dryports. Port regionalization as a planning challenge - The case of Hamburg, Germany, and the Süderelbe

This paper emphasizes dryports in the context of port regionalization. It specifically deals with dryports as a challenge for planning, policy and metropolitan governance in the vicinity of seaports. The starting point is the ongoing spatial shift of terminals, distribution centres and port related developments towards the hinterland of mainports and the associated planning conflicts, raising negative impacts such as congestion, land consumption, land use conflicts and neighbourhood conflicts. The paper discusses these challenges against the empirical case of the Süderelbe-region in the Southern hinterland of the port of Hamburg, Germany. It focuses on the often neglected yet highly controversial issue of land use and related traffic flows. Further it reveals how these conflicts are being managed at the regional level. The main contention of the paper is that port regionalization triggers substantial planning conflicts different from those that are known from core port areas, due to the associated demand for land and infrastructure and also as a result of the often poorly developed institutional framework to solve these problems.

Biofuel refinery location and supply chain planning under traffic congestion

This research focuses on planning biofuel refinery locations where the total system cost for refinery investment, feedstock and product transportation and public travel is minimized. Shipment routing of both feedstock and product in the biofuel supply chain and the resulting traffic congestion impact are incorporated into the model to decide optimal locations of biofuel refineries. A Lagrangian relaxation based heuristic algorithm is introduced to obtain near-optimum feasible solutions efficiently. To further improve optimality, a branch-and-bound framework (with linear programming relaxation and Lagrangian relaxation bounding procedures) is developed. Numerical experiments with several testing examples demonstrate that the proposed algorithms solve the problem effectively. An empirical Illinois case study and a series of sensitivity analyses are conducted to show the effects of highway congestion on refinery location design and total system costs.
